A kid should count on his mother to take care of it: a woman knows the child she gave birth to is hers. Women, on the other hand, can never be absolutely confident whether they are the child’s true parent.

And a first born child usually look like a father appears to have an evolutionary edge: he will persuade his dad to hang on to take care of things.

There is some sort of work to back up this hypothesis. A 1995 research published in Nature showed that strangers told a child’s mom or dad to match photos of one-year-olds had even more luck matching an infant with a parent.

Interestingly, when participants were told either mom or dad to suit 20-year-olds, they were unable to do so.

Solid evidence, it would seem, that the babies really appear more like their father than their mother — and that they are wearing it over time.

Furthermore, the research just focused at children born to single mothers, and these kids did not stay with their dads — a condition where dads seem to be more unsure over their paternity.

And when you think about newborns who look like their dads, it really makes common sense, too.

child look like a father

And though looking a lot like your dad is a benefit for most people, it may have been catastrophic in our more barbarous history for a child who was not directly linked to their mother’s father.

That takes us to the new and perhaps most convincing theory: in fact, babies do not look much like their dad. But everybody, particularly the mother of the boy, is involved in persuading the child’s father to be his spitting image.
